Implication

Feline slope-walking data should not yet guide human gait interventions; leaves open fascicle-MTU decoupling in locomotion mechanics.

Population

Adult female cats (Felis domesticus), n=5, mean body mass 3.3 kg (SD 0.4)

Intervention

Overground walking at various slopes (+/- 25, +/- 50, +75, and +100%)

Comparator

Level walking (0% slope)

Outcome

Muscle fascicle length changes and velocities compared with length changes of the whole muscle-tendon unit (MTU)surrogate

Muscle fascicle length changes in feline ankle extensors are highly dependent on slope and muscle architecture, demonstrating that MTU length is not a reliable indicator of muscle spindle strain during locomotion.

Limitations

Cats had difficulty walking at a steady pace at the 75 and 100% downslope conditions, so only upslope walking data are reported for these conditions
One cat (cat 1) was tested in only three slope conditions, walked slower, and had to be excluded from the main statistical means
Low amplitude EMG for MG during downslope walking prevented processing of these data
